Guernsey

Has anyone in Guernsey been allowed to do this?

The island's planning register, searched the way someone with a plan searches it: by the kind of work, by where, and by your own words. 3,350 applications are in here.

The ones that were refused

More useful than the approvals: this is what the island would not accept.

A precedent is not a permission. Two identical applications a street apart can be decided differently, and the register does not carry the reasons — for those you need the officer's report on the island's own planning site.
